Without those other "negligible" aspects there is no incentive for anyone to run nodes to validate the chain. There is no blockchain. It's those very things that allow these systems to function.
I completely agree with you. I'm just saying that there's a loophole when you're dealing with people who are obsessed with doing "blockchain for ____". If they understood blockchain from a technical perspective, they'd understand that it makes no sense for their application.
You can still work with those people if you revise the definition for "blockchain" in your mind into something that isn't really a blockchain.
Oh boy. If people think this is an example of being unacceptably direct and gruff, I need to reexamine the way I talk during technical discussions.
I've always thought it best to just cut straight to the core of issues like he's doing. I suppose it's a jerk move to corner people into admitting they're wrong even when it's obvious. Maybe there's a nicer jedi-mind way to do it.
The analogies damage this article because they feel wrong. For example the "never synchronous" example is more like this:
You order a burger at the cashier window, then go to the pickup window. If the burger is already made, it's already at the pickup window when you get there.
The author wants a special case where if the burger is already made, they hand it to you immediately at the cashier window. This might seem more efficient, but both in the restaurant and in code it makes logic way more complex.
Exactly. If for some reason my promise is immediately fulfilled (e.g. the result was previously memoized), I don't want to provide an alternate codepath to handle the result.
Absolutely, click "No extra automation" on the last version and play it normally. It makes you question everything you previously thought was a random guess. Makes the game vastly better, because you're richly rewarded for thinking through every possibility. And you're incentivized to spend time thinking because you're not punished when it ends up being a truly random choice. Great, great work. Too bad minesweeper is not suited to mobile devices because I'd play this version all the time.
I see no reason to consider that, though. You'd have to say that, not only the US dollar, but every paper currency is crashing, along with gold. That seems quite a stretch.
That is exactly what the cryptocrazies are stipulating. It's cryptocurrency vs fiat. Seen from the fiat perspective, it's an obvious bubble. But if you're on the cryptocurrency side, it's barely the start of a massive and inevitable shift.
I think there are so many kids that did well in science and math and love science fiction and probably enjoy dabbling in some kind of tech libertarianism and have a certain naïveté about cryptocutrencies and what will happen in society. I mean this in a nice way but the view that the apparent obscene volatility of cryptocutrency is a sign of it's stability and the USD is crashing, is an intensely delusional view. That really cannot be understated.
This has always been a worry in the traditional stock market. With a stop loss order you're basically creating a "secret" order to sell at below market value. Anyone who knows about it has a direct incentive to profit from it.
Stop-losses are very important in investing but I'd recommend always executing them manually at market rate. Set a price alert to notify you. Of course if the exchanges are down you're sol, but if BTC is on a bullet train to $10 your exchange stop-loss probably won't fill at your price anyway.
"Stop-losses are very important in investing but I'd recommend always executing them manually at market rate."
No, no, no, no ...
You do not ever want to insert a market order[1] ... the market can be manipulated and high frequency traders can buy/sell your public market order at an artificially low/high price.
The answer to getting "stopped out" is not to insert a market order - it is to create a fill-or-kill at a specific price or other more specific order type ...
Stop loss means get out NOW to stop losses. Trying to finesse a nickel out of a trade at that point is a sucker's game.
Getting "stopped out" is fine, it's part of investing. You need to stop your losses. I'm just saying don't put the order on the books for the exchange to pluck like a ripe berry.
